TOY.

Specification of Letters Patent, Patented Sept, 9, 1919.

Application filed Januar ie, 1919. Serial m. 271,415.

To all whom it may concern:

Be it known that I, Trmononr. Sironrnsnr, a citizen of the Republic of Austria, residing at Gary, (Indiana, box 10,) in the and State of Indiana, have county of Lake invented certain new and useful Improve ments in Toys, of which the following is a advantages of the incompanying drawings which form a part of this specification and illustrate the preferred embodiment of the invention.

In the drawings: Figure 1 is a top plan view of my invention.

Fig. 2 is a front elevation thereof with portions sectioned substantially on line 22 of Fig. 1.

Reference numeral indicates generally a wooden frame comprislng spacedlegs 11 and 12 and uprights 13, 14, 15 and 16 dis posed in pairs spaced from each otherto support parts to be described. A power shaft 17 is horizontally journaled in uprights 14 and 15 near the upper end of the frame and a pivot shaft 18 is similarly mounted for rotation in the opposite pair of uprights 13-16, shafts 17 and 18 lying parallel with their axes in the same horizontal plane. A sector shaped block of wood 19 is fixed near its axis upon power shaft 17 with its arcuate edge turned toward the center of the frame. A similar sector shaped piece of wood 21 is mounted for oscillation upon pivot shaft 18 and has its arcuate edge projected toward piece 19, the pieces 19 and 21 being disposed in a common vertical plane at the transverse center of the machine. Centrally of the machine and between legs 11 and 12 is )ositioned an anvil 22 adapted to be struck y hammer 23 having vertical side guides 24 which slide in guideway 25 vertically positioned in a recess 26 provided in the frame for reciprocation of the harm mer. At the top of recess 26 the frame is from the following dedriving rod 35.

provided with a plurality of rubber bumpers 27 adapted to receive the shock of upward recoil of hammer 23.

By means of a pin 28 a cylindrical hollow post is secured to hammer 23 and extends upwardly from the center thereof through and aroundhole 31 bored vertically through the center of frame 10. Telescoped within post 29 is a hollow thrust bar 32. A helical spring 33 is positioned within post 29 and compressed between the hammer 23 and a block 34 carried in the lower end of thrust bar 32. The upper end of thrust bar 32 is secured in any suitable manner to the lower end of and in alinement with a driving rod 35 which extends vertically between the sector shaped pieces 19 and 21. An operating,

handle 36 is fixed by one of its ends as at 37 to the power shaft 17, the free end of the. operating handle being provided with a hand grip 38 and extending preferably across the machine to the side opposite from shaft 17.

Similar racks 39 and 41 are secured to and vertically disposed upon the opposite sides of the driving rod 35 and are respectively engaged by gear teeth 42 and 43 attached respectively to the sector shaped pieces 21 and 19'. Gear teeth 43 communicate the power of handle 36 to rack 41 and thence through driving rod 35, thrust bar 32, spring 33 and post 29 to hammer 23 to drive the hammer down against the anvil. Sector shaped piece 21 through the medium of gear teeth 42and rack 39 acts as a guide for When the hammer has been driven down toward the anvil it is upwardly reciprocated and normally held at the upper end of its stroke by means of springs 44 and 45 which are interposed between the frame and the lower extremities respectively of sector shaped pieces 21 and 19.

I conceive the construction of racks 39 and 41 and gear teeth 42 and 43 to be novel. It is to be noted that these racks and gear teeth are formed of strips of sheet metal mutilated between dies to give them the shape of rack teeth or gear teeth according to whether the teeth formed by the dies are alined as in. racks 39 and 41 or arcuately positioned with respect to each other as in the case of gears 42 and 43. The racks or sets of gear teeth formed thus by punching up strips of sheet metal are attached readily to wooden parts such as the driving rod 35,

the sector shaped pieces 21 and 19, by driving nails 46 through the sheet metal between the teeth and into the wood. This forms a very cheap construction for use in the manufacture of toys and light articles of machinery.

In the operation of the invention it is to be understood that the springs 454s and 45 may be so tensed as to hold the hammer and the driving rod 35 together with the ass0- ciated parts in the full line position of elevation illustrated in Fig. 2, or thatthe springs may be built more strongly causing them to normally hold the hammer and. driving rod elevated to such a degree that the hammer is in contact with the rubber bumpers 27. Assuming that a. child wishes to crack nuts by the use of the toy power hammer herein described, he places the nut 29' to be cracked upon anvil 22, and grasping handle 30, forces it downward from the full line position toward the dotted line position of Fig. 2. This resultsin driving hammer 23 downwardly toward and against 25 anvil 22 as indicated in dotted lines, the power applied to handle 36 being conveyed through power shaft IT, sector shaped piece 19, gear teeth 413, and rack teeth 41, to driving rod 35 and thence through thrust bar 32, spring 33, and post 29 to hammer 23. Separation of rack teeth 41 from gear teeth 43 is prevented by the enmeshed relation between rack teeth 39 and gear teeth 42 on the opposite side of the driving rod. It will be noted that, because of the interposition of spring 33 between thrust bar 32 and hammer 23, the latter is resiliently driven against the anvil. In this manner, while a sufiicient degree of power is exerted against the anvil to satisfy the ordinary childish desire for amusement, the fingers of the child are protected from serious injury in case they are carelessly insorted between the anvil and the descending hammer.

While I have illustrated and described the preferred embodiment of the invention it will be obvious that one skilled in the art may make modifications thereof without departing from the spirit of the invention. I wish therefore not to be restricted to the precise embodiment shown except in so far as the same is limited in the appended claims.

I claim:

1. The combination with a frame, of a hammer mounted for reciprocation therein, a driving rod connected to the hammer, opposite side racks fixed upon the driving rod, and a pair of gears meshed respectively with said racks and pivoted one on each side of said driving rod.

2; The combination with a frame, of a hammer mounted for reciprocation therein, a driving rod connected to the hammer, opposite side racks fixed upon the driving rod, and a pair of gears meshed respectively with said racks and pivoted one on each side of said drivingrod, said hammer being resiliently connected to the driving rod.

3. The combination with a frame, of a hammer guided for vertical reciprocation therein, a driving rod connected to said hammer and vertically disposed above the same, racks positioned respectively on opposite sides of said driving rod and extending longitudinally thereof, a pair of gears respectively meshed with said racks and pivoted in the frame on parallel axes on opposite sides of the driving rod, and springs compressed between the frame and said gears to hold the above described parts normally in an elevated position.

In testimony whereof I have afiixed my signature.

THEODORE SMOLINSKY.
